Azure Service Management ASM and ARM Overview

What is Azure Service Management (ASM)?

• Azure Service Management (ASM) is the initial Azure deployment service that allows you to deploy and manage Azure resources.

• It moved to GA (general availability) with azure in 2010 and did not adopt a modular approach to resources.

• Azure Classic virtual machines deployed by ASM can be used in both classic and new Azure portals.

Some of the challenges with ASM are:

- Serial processing - which means that ASM allows resources to individually create resources such as a virtual machine, network, storage, and so on.

- Hard coded resource dependencies

- No role-based access control (RBAC)

- No resource group

- No marking of your resources on your solution

- Deleting or deleting resources is not easy

What is Azure Resource Manager (ARM)?

• Azure Resource Manager (ARM) is the successor of ASM. It allows you to deploy and manage azure resources more efficiently.

• ARM passed the GA in 2015 and adopts a modular approach to resources.

• VMs deployed and managed by ARM can only be used on the azure portal.

• Microsoft recommends deploying and managing the resource using Azure Resource Manager.

Some of the ASM issues resolved with ARM

- Parallel processing

- Deploy resources using templates

- Resources are not tied to other resources

- Role Based Access (RBAC)

Benefits of Azure Resource Manager

• Deploy, manage, and monitor all resources in your solution as a group.

• Redeploy your solution throughout the development cycle.

• Manage your infrastructure using templates rather than scripts.

• Dependencies defined by the administrator.

• Apply access control to all services in your resource group.
